论文摘要
在状态更新系统中，状态更新过程所携带的多个功能需要追求以更新信息年龄来衡量的及时性之外的目标。我们考虑了这样一个问题，即发射器通过无嘈杂的二进制二进制能源收集渠道发送状态更新消息，该通道等同于定时渠道。发射器旨在扩大或掩盖更新过程中携带的能量状态信息。接收器提取编码的信息，在保持状态更新的及时性的同时，渗透能量状态序列。因此，必须设计更新的时间来控制消息速率，能源状态不确定性和信息时代。我们调查了可实现的速度，能量到达状态不确定性的降低和信息时代之间的三向权衡，以零和无限的电池案例。
In status update systems, multiple features carried by the status updating process require pursuit of objectives beyond timeliness measured by the age of information of updates. We consider such a problem where the transmitter sends status update messages through a noiseless binary energy harvesting channel that is equivalent to a timing channel. The transmitter aims to amplify or mask the energy state information that is carried in the updating process. The receiver extracts encoded information, infers the energy state sequence while maintaining timeliness of status updates. Consequently, the timings of the updates must be designed to control the message rate, the energy state uncertainty, and the age of information. We investigate this three-way trade-off between the achievable rate, the reduction in energy arrival state uncertainty, and the age of information, for zero and infinite battery cases.
